Where do we go from here? Most deployments are not “greenfield” OCS 2007 R2 Lync 2010 Migrations

Most deployments will have some sort of integration with ancillary communications systems Third party telephony systems Messaging or Exchange UM considerations

Initial Planning DecisionsOn-premises or online deployment? When should I choose an "On-Premises" solution?

Physical or virtualized topology?Lync Server performance on virtual topologies can vary greatly depending on the workloads being used, the number of users, and the host hardware.

Conferencing? Web conferencing, A/V conferencing, Dial-in conferencing

High availability?Enterprise Edition pools make it possible for Lync Server to continue functioning even if a server is unavailable. Standard Edition servers can be paired for high availability

Disaster Recovery?Pool pairing enables the servers at one datacenter to pair with a corresponding pool at another datacenter. If one datacenter goes down, the other pool in the pair can service users in both pools with minimum interruption of services.

Initial Planning DecisionsCommunicate and collaborate with external users? Whether with corporate users who are connecting externally or federated partners & customers

Enterprise Voice?EV provided a viable alternative to traditional PBX-based telephony systems where users will be able to place calls from their computer or desk phone

Persistent chat?Enable users to have real time conversations that can persist over time.

Microsoft Exchange deployed? Synergistically enhancing features (Exchange UM) enable users to receive/listen to voicemail, and integrate the personal contact stores (requires Exchange 2013)

branch offices in your organization? Ensure service resiliency for voice

Lync topologies

Topology – What does that Mean?Webster’s Dictionary

Topology is defined as a branch of mathematics concerned with those properties of geometric configurations unaltered by elastic deformationsTopology is defined as the configuration or “design” of an organism or system

WikipediaTopology is defined as the arrangement of various elements (links, nodes, etc…) of a computer network.

Microsoft The configuration formed by the connections between devices on a local area network (LAN) or between two or more LANs.

Deployment Options

Lync On-PremisesWhen should I consider an on-premises deployment?

An on-premises deployment is best when… Full Enterprise Voice Capabilities

An on-premises Lync Server deployment is required if you are planning to replace your PBX or which uses advanced calling features.

Media Quality ControlsRequired for full range of media quality assurance features, (i.e. Call Admission Control (CAC) Quality of Service (QoS) )

Persistent Chat On-premises required

An on-premises deployment is best when… 3rd-Party Server Applications

Required to work with trusted 3rd-party applications that use the Microsoft Unified Communications Managed API (UCMA).

Multi-National/Multi-Regional Companies Needing Regional Support

Datacenters in multiple countries or regions and need servers to be deployed and managed on a regional basis

Complete control over policies, reports, and upgrades

full set of server & client policies, Monitoring reports, and control of upgrades.

Lync On-Premises Forest Models

Multiple AD topologies supportedLync in a single AD forestLync in a resource forest scenario + 1 user forestLync in a resource forest scenario + multiple user forest

Lync onlineWhen should I consider an online deployment?

An online deployment is best when… Full Enterprise Voice Capabilities are NOT required

An on-premises Lync Server deployment is required if you are planning to replace your PBX or which uses advanced calling features.

Media Quality Controls are NOT requiredRequired for full range of media quality assurance features, (i.e. Call Admission Control (CAC) Quality of Service (QoS) )

Persistent Chat is NOT requiredOn-premises required

Lync onlineLync Online Multitenant (Office 365-S) is the Microsoft public cloud offering for LyncLync online topologies:

Lync online + Exchange online -> limited functionalitiesLync online + Exchange onprem -> UM and Exchange archiving not supported

Voice in the cloud:Business Voice -> Enterprise Voice in the Office 365-S cloudSyndication partners -> Previously called Lync to phone

Lync 2013 Hybrid Deployment Requirements

Component Description NotesOffice 365 DirSync Synchronization of on-premises Active Directory

with Office 365Common requirement with Exchange

Active Directory Federation Services (AD FS)

Single sign-in (SSO) authentication infrastructure; end users get Office 365 services with on-premises credentials

Common requirement with Exchange

Lync 2010+ Federation Edge

Interoperability between online and on-premises is built on the federation framework

Coexistence between online and on-premises IM/Presence Conferencing

Lync 2013 admin interface

Cross-premise migration is available through Lync Management Shell

Admin interface can be used to move 2010 or 2013 users directly to online

Lync 2013 pool for Hybrid Voice features

Hybrid Voice with E911 and Media Bypass require that a Lync 2013 pool/server be deployed on-premises

Only required for these two specific hybrid voice features

Lync hybrid ConsiderationsHybrid as a temporal state

Migration scenario to the cloudPart of the user population only needs basic features

To setup hybrid customer needs to start onprem first and then move users to the cloudHybrid voice was discontinued, no split workloads allowed

“Jajah Voice”, the Lync-to-phone service provider for Office 365, was discontinued August 31, 2013.

Service providersO365 Multi-Tenant

Service Provider HostedSingle tenant private cloud (SIs, Telcos, SPs, but also government agencies)Current challenges for the Service providers:

AD topology. Resource forest scenario is beneficial for the SP but leads to 3 forest and the necessity of split domain

No split domain with a service providerNo guidance from Microsoft

Customers that require full EV capabilities and want to go cloud today have the option to go to a service provider

Lync resource forest + Exchange online

The three forest topology limitationsExchange UM will not workTwo resource forest that don’t know anything about each otherManually keep the UM dial plan in sync with the Lync dial planTwo versions of the directory synchronization toolNo trust between the Lync and the Exchange forests

Questions?

Summary

SummaryThe first major decision is how to deploy Microsoft Lync: as Lync Server 2013 on premises, or Lync Online with Microsoft Office 365 in the cloud.What features and capabilities are required?Business drivers provide requirements that will

determine topology What is your strategy?Short and long term strategy & statements of directionI.E. Virtualization, moving to a cloud consumer model, Business drivers provide requirements that will determine topology
